RAZOR.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed April 13, 1912. Serial No. 690,467.

To all whom it may concern:

Be it known that I, GUlY D. DE Lorenzo, residing at Utica, in the countyof Onei and State of New York, have invented a new and useful Razor, ofwhich the following is a specifica ion.

My invention relates to a razor, and I declare the following to be afull, clear, concise, and exact description the reef sutficient toenable any one skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings in which likereference characters refer to like parts throughout the specification.

The object of the invention is to provide a razor having a lockingdevice that will be of simple construction, efficient and adapted moreparticularly for holding a razor blade securely in closed positionwithin the handle.

The device embodies a plunger adapted to engage a suitable notchdisposed in the end of the blade of the razor. Said plunger is heldnormally in position to engage said notch in said blade by a coiledspring housed in a recess provided in an end member of the razor.

Other features will appear by reference to the drawings in which:

Figure 1 is a perspective view of a razor, showing the blade in partlyopen position; Fig. 2 is a side elevation of the razor, showing parts insection; Fig. 3 is an enlarged fragmentary detail View partly section ofone end of the razor, showing the locking mechanism; Fig. 4 is a detailview showing a transverse section along the line l4 of Fig. 1; Fig. 5 isan enlarged detail view, showing a perspective of a plunger employed,one head, being removed therefrom; Fig. 6 is an enlarged detail view ofa modified form of head; Fig. 7 is an enlarged fragmentary View of oneend of the razor, showing a vertical section thereof along the line 77of Fig. 3; Fig. 8 is a perspective view of an end member employed; Fig.9 is an enlarged perspective view of apivot employed; Fig. 10 is anenlarged perspective view of a modified form of pivot employed, showinga washer removed therefrom; Fig. 11 is a detail View of a washeremployed; Fig. 12 is an enlarged form of modified pivot employed,showing a washer removed therefrom; Fig. 13 is a fragmentary view of ablade, showing an attachment for aid in honing the razor; Fig. 14 is anend-view of the blade, enlarged, shown in Fig. 13;

Fig. 15 is an enlarged end View of the attachmentto aid in honing therazor; Fig. 16 is an enlarged View of a screw employed to hold anattachment to the blade of the razor.

Referring more particularly tothe drawings, the upper and lower parts ofthe handle of the razor are represented by 1 and 2, respectively. Blade3 is fulcrumed to one end of parts 1 and 2 by a pivot 4, whose ends maybe reduced at 5 and 6 to form shoulders whereby washers 77 may bemounted thereon and secured by hitting the ends of pivot 4 and therebyspreading same. However, the ends of pivot 4 may be of the samecircumference as the body of the pivot as seen at 8 in Fig. 9, for theassembling of washers 7, which are held thereon by spreadin the ends asbefore described.

Phe ends of parts 1 and 9. of the handle of the razor opposite to thoseto which blade 3 is fulcrumed are held together, with member 9,therebetween by a pivot 4 and washers 7 as heretofore described withreference to the opposite or remote end of the razor.

Member 9 may be made of celluloid, aluminium, rubber or the likematerial and is provided with arecess 10, disposed a little to one sideof its longitudinal center. Said recess 10 is adapted for the receptionof a coiled spring 11 hearing at one end against the rear wall 12 ofrecess 10 and at the other end against plunger 13, formed to slide inslots 1414 disposed directly opposite each other and in centrallongitudinal alinement with recess 10 of member 9, in parts 1 and 2 ofthe handle of the razor. tend rearwardly from edge 15 of member 9sufliciently farpso that plunger 13 may be moved clear of edge 15 ofmember 9 to release blade 3 of the razor. Furthermore, said slots 14C14are of narrower width than recess 10, whereby spring 11 disposed in saidrecess may be held normally in a direct line with its trend of pressure,so as not to be crowded up or down therefrom into slots l4lt.

Plunger 13 is formed with a head 16 and a lower shouldered part 17,whereby lower head 18 having a square aperture 19 may be assembledthereto by hitting the end of shoulder part 17 and spreading same. Saidheads 16 and 18 may be formed oblong in shape as seen'in Fig. 5, wherebythere will be exposed a greater surface for the fingers to touch, whenmoving the plunger 13, or

Slots 14 -ex-' said heads may be formed of circular shape asfor neatnessof appearance. The upper or exposed surface of heads 16, 18 and 20 arecorrugated as seen in Fig. 5 for the purpose of preventing the fingerfrom slipping thereon,-when actuating the plunger 13.

In Fig. 2 heads 16 and 18 are shown fitted to plunger 13 at right anglesto the body of said plunger, whereby to conform to a flat surface ofparts 1 and 2 of the razor. In Fig. 7 heads 16 and 18 are disposed onplunger 13' at an angle, whereby to conform to the curved surface ofparts 1 and 2 of the handle of the razor. In each instance, heads 16 and18 are disposed upon plunger 13, so that their under surface ,will beflush with the upper surface of parts 1 and 2 of the handle, to therebyobviate any awkward protruding surface. 3

The operation of the lock is obvious. Blade 3 of the razor is pushedinto closed position, whereupon plunger 13, at the proper moment ofcontact, will engage the outer end of said blade 3 at about the locationindicated by 21, and will ride along said edge of said blade 3 untilnotch 22 thereof is reached, whereupon spring 11 constantly urging saidplunger 13 outward, will force same int-o said notch 22 to therebyrigidly hold said blade 3 in closed position until the operator desiresto open oa=- draw out said blade, whereupon he manipulates the plungerby touching heads 16 and 18 disposed onhopposite ends thereof and drawssaid plunger 13 rearward into slots ]414, to clear notch 22 of blade 3.Spring 11 is held in recess 10 of member 9 by plunger 13, which isassembled, after the spring is disposed in recess 10, by placing theshouldered end of said plunger 13 through slots 14-14 and securing underhead 13 to said shouldered end. There is disposed on either side ofblade 3 about pivot 4 on which said blade 3 is fulcrumed, washers 2525which are countersunk in parts 1 and 2 of the handle and are designed tolessen. the wear of the swinging blade 3 ,uponparts 1 and 2.

lt' will be observed by reference to Figs. 3 and 10 that the pivot *1,which secures the ends of parts 1 and 2 of the handle opposite to thoseon which blade 3 is fulcrumed, is dispcsed therein, so as to aline withhole 26 of member 9. in which hole 26 is located,

whereby to counteract the backward pressure that spring 11 exertsagainst member 9. Member 9 may also be prevented from turning under thepressure of spring 11 by employing a square rivet 28 which is held inassembled position by washers having square apertures 29.

In order to prevent edge 30 of the razor from becoming worn, which tendsto render the honing of the edge of the blade difficult, there may beemployed cap 30 having projections 3131 adapted to lit intocorresponding recess 3232 formed on either side of the blade adjacentedge 30 thereof. Cap 30 is provided with projections 33 33, whereby samemay be easily slid or drawn off from its position on blade 3, which inthis instance is reduced, as shown by the dotted line in Fig. 13,whereby the outer edge of cap 30 will lie flush with the edge 30 ofblade 3. Blade 3 is provided with an aperture 35 adapted to suspend therazor from a convenient peg or hook.

A small screw may be employed to hold cap 30 from longitudinal movementon blade 3, whereby the cleaning of the razor blade will not remove theattachment.

Having thus described my inventiomwhat I claim as new and desire tosecure by Letters Patent is:

In a razor, the combination of a handle comprising an upper and a lowermember, an end member disposed between said upper and lower members, asquare rivet for holding said end member in assembled position relativeto said members of said handle, a blade pivotally secured to saidhandle, a notch in the end of said blade, a cam surface on the end ofsaid blade adjacent said notch, narrow alined recesses in the upper andlower members of said handle, a re cess in said end member, a plungeradapted to be slidingly mounted in said recesses, and a spring disposedin said recess in said end member, whereby to hold said plungernormallyin engagement with said notch in said blade.

I11 witness whereof I have hereto signed my name in the presence of twowitnesses.
